求助：Ubuntu12.10 安装eclipse 配置c++环境问题

[WinChan]

我是在Ubuntu软件中心安装的Eclipse，版本是3.8 根据网上的教材，进行到以下红字部分，提示冲突。

打开Eclipse,打开Help->Install New Software,然后点击Add按钮,在弹出的对话框中
Name项填入CDT
Location项填入http://download.eclipse.org/tools/cdt/releases/indigo
点击Ok按钮,在下边出现的列表中,
第一个CDT Main Features基本都要安装
第二个中务必要把包含GNU字眼选择安装

以下为提示冲突内容，请指导！

建议不要用软件中心的版本，建议直接从官网下绿色版的，升级什么的方便许多。
